Answer:
the top right is the only function
Step-by-step explanation:
a function is defined as any set of points for which one x value only has one y value
Answer:
M<GEF=30
M<DEF=40
Step-by-step explanation:
First you want to solve for x. to do that you put both of the equations together and make it equal to 70 since M<GED=70. so you would get 2x+10+5x-10=70.
when you solve that you get x=10. next you substitute x with 10 in the other equations to solve for the unknown measure angle. So M<GEF=2(10)+10 and M<DEF=5(10)-10. When you solve that you get M<GEF=30 and M<DEF=40. you can check this by adding them together and they add up to 70 which is the M<=GED.
4 × 3 = 12
9 × 1 = 9
12/9 as a mixed number - 1 3/9
1 3/9 simplified - 1 1/3
1 1/3 is your answer.
Glad I could help, and good luck!

The easiest way to solve this problem is to multiply first, then cut in half.
1.25 times 4 is 5.
5/2 is 2.5.
You could also do it the slightly more difficult way:
1.25/2 is .625.
.625 times 4 is 2.5.
Answer:
Shop A = 113 pence
Shop B = 101 pence
Step-by-step explanation:
Given :
Shop A :
5kg for £5.65
Shop B:
2kg for £2.02
Price per kg :
weight / price
100 pence = £1
Shop A :
Price of 1kg :
5.65 / 5 = £1.13 = 113 pence
Shop B:
2.02 / 2 = £1.01 = 1.01 * 100 = 101 pence
